Technology Process of SIALON

There total 2 articles about SIALON which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

kaolin (1332-58-7) + silica + nitrogen (7727-37-9) + silicon (7440-21-3) → Al0.2N1.8O1.2Si1.8, low temperature (112760-32-4)

Guidance literature:

In neat (no solvent, solid phase); milling kaolin, Si and SiO2 for 20 h in hexane, drying, pressing into disks (8 MPa), heating at 1270°C for 8 h (10% H2 in N2);

DOI:10.1111/j.1151-2916.1998.tb02605.x

Reference yield:

yttrium(III) oxide + aluminium nitride + silicon nitride + alumina → AlNOSi, α (112760-32-4)

Guidance literature:

In neat (no solvent); the mixt. milled for 4 h in 2 -butanol, dried mixt. with soln. of dispersant (Hypermer KDI), milled for 4 h, sintered in a graphite fura=nace under N2, heated at 1200°C at a rate of 20°C/min, followed by a 0.5 h hold, 2 h at 1750°C;
